When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 5c - c = 2c - 8y - 1 for c in terms of y.
| \(\frac{1}{2}\)y - \(\frac{2}{7}\) | |
| -\(\frac{2}{3}\)y + \(\frac{1}{3}\) | |
| 3y - 4 | |
| -2\(\frac{1}{3}\)y - \(\frac{1}{3}\) |
